2005 Fuel Economy data has been released.
U.S. EPA's Office of Transportation and Air Quality (OTAQ) protects public health and the environment by controlling air pollution from motor vehicles, engines, and the fuels used to operate them,
and by encouraging travel choices that minimize emissions. These "mobile sources" include cars and light trucks, large trucks and buses, nonroad recreational vehicles (such as dirt bikes and snowmobiles), farm and construction equipment, lawn and garden equipment, marine engines, aircraft, and locomotives.
Transportation and Air Quality key topics are:
Overview: Pollutants and Programs: Information on how much air pollution and greenhouse gases are emitted by mobile sources, the programs OTAQ has undertaken to control these emissions, and the impact of those programs on air quality and climate change.
Consumer Information: Learn what you can do to help reduce air pollution and how to buy the
cleanest, most fuel-efficient vehicle that meets your needs.
On-road Vehicles and Engines: Information about highway vehicles (cars and light trucks, heavy
trucks, buses, and engines, and motorcycles): fuel economy, emission
standards and regulations, emission recall programs, new vehicle certification and in-use vehicle compliance, inspection and maintenance
programs, diesel retrofit programs, evaluating the benefits of inventions
designed to reduce emissions, and importing vehicles to the United States.
Nonroad Engines, Equipment, and Vehicles: Information about aircraft, locomotives, diesel and gasoline boats and ships, personal water craft, lawn and garden equipment, agricultural and construction equipment, and recreational vehicles (e.g., dirt bikes, snowmobiles): emission standards and regulations, certification and compliance, and diesel retrofit programs.
Fuels and Fuel Additives: Information on diesel, gasoline, and alternative fuels for mobile sources, fuel quality control programs, the requirements for registration and health effects testing of new fuels or fuel additives, and reporting forms.
Voluntary Programs: Information about voluntary programs to reduce air pollution associated with transportation and other mobile sources, including commuter choice programs, diesel retrofit, choosing a cleaner car or truck, and
other initiatives.
Transportation and Air Quality Planning: Information on the ties between land use and transportation planning, and air quality. Topics includes conformity, State Implementation Plans (SIPs), transportation control measures, and available funding and grants for implementation of such programs.
Modeling, Testing, and Research: Information on OTAQ models for estimating emissions from on-road vehicles, nonroad sources, and fuels; information on how EPA tests and measures emissions; and information on OTAQ research into advanced technologies.
Fuel Cells: Information on EPA's program to encourage progress in the applicaton of fuel cells for powering cars and other vehicles.
